How do key modern philosophers like Sartre and Marx understand the question-What do you think of them?

CONTEXT

Today’s culture is rife with clichés and preconceptions about freedom, beginning with the idea that freedom is nothing more than the ability to “do what you want.

This course has modestly attempted to go beyond this simplified view to explore the conditions and limits of freedom.

But the subject remains inexhaustible and complex. Rousseau, an 18th-century philosopher, had this to say about freedom: “Man is born free and everywhere he is in chains.

Spinoza, a 17th-century philosopher, said this about freedom: “Such is the human freedom that all men boast of having, and which consists only in those men are conscious of their desires and ignorant of the causes that determine them.

For the THEORY paragraph, explain the answer that Marxism or Sartre’s existentialism would give.
